Subject: [PATCH] arm64: dts: rockchip: change eth phy mode to rgmii-id for
orangepi r1 plus lts
commit a6a7cba17c544fb95d5a29ab9d9ed4503029cb29 upstream.
In general the delay should be added by the PHY instead of the MAC,
and this improves network stability on some boards which seem to
need different delay.
